MANURE- SPREADER To whom it may concern:

Be it known that I, JOHN D. CURTIS, e citizen of the United States, residing at 1ifll'orcester, in the county of Worcester and Commonwealth of Massachusetts, have invented a. new and useful lniprovernent in lvlenure-Spreeders, lont which the following is :r specification, accompanied by drawings forming, e part of the seme.

My invention relates to thet class of vInunure spreaders in" which e movable bottom is employed to move the load slowly to e revolving bester et the rear end of the spreader by Which it is distributed over the ground. ln spreaders of this type it is'custernary to move the load in e solid mass within the path of the beater teeth, by which the leed is shredded and thrown rearwardly over the ground. In .machines of this type also, the axle is usually journaled below the sills ol the body which raises the body too high for convenient loading, es the manure to be raised above' the sides of the body, or' in cese the reer eXle is inclosed in the beater, the construction becomes complicated and e. considerable portion of the spreader must ,be dismantled in order to remove the. rear e-Xle or the beer. In spreaders' of this type the resistance to the rotation of the beater is considerable owing to the compeet mess clogging the movement of the bester, andr addingA materially to the draft. lt is one of the objects of my invention `to overcome these objections by Ineens oi' e suspension of the body roinzthe rear axle which l journal above the sills but beneath the :movable bottom.

lily 'invention has for its further object to provide for e, Simple, strong end cheep construction of the 'body portion 'of 'the spreader-by the employment of steel sills in single continuous channel bers extendingl from the rear to the .trent end of the spreader, with the forward ends oic the sills ,bent upwardly end joined et their forward ends'by e. cross ber, of the sume length es 'the Width of the body.

Another object of my invention is to provide e.. substantiel support mounted upon the upturned ends for the heed board. .4

The construction by which these Several objects, among others, are secured, is hereinefter described, the novel features being` pointed out in the annexed claims.

Referring 4to the accompanying drawings,
